Surface Blowdown Connection
Surface Blowdown Connection
(OP)
I have a scotch marine boiler that has a 1 1/4" surface blowdown connection. Can anyone tell me if I can step down and use a 3/4" metering valve on this connection or does it have to be 1 1/4"?





RE: Surface Blowdown Connection
In all Fairness,I understand this should not be reduced as it must be the design requirements of certain%age blowdown;
that may not be achievable with reduced dimensions
of lesser Cross-sectional area available for flow actually(almost half or even lesser).
